the crappiest job

i used to work as a cashier at the px by my house during my senior year in high school. i made about $7.25 so it wasn't too bad except for those few choice customers...
to elaborate: one morning before i was supposed to go to work i had a nosebleed that lasted for maybe half an hour, so i wasn't in the best of moods. (aside from not being a people person to begin with) i get a customer, ring up her items and do the whole cashier thing. she said "hi" to me, and i mumbled one back. apparently that wasn't good enough for her, so when i was done with her transaction she asked to speak to a manager.
i call for one, they were busy at the moment, so she started bitching to a supervisor, then my mom (a manager) listens in to her complain to the supervisor which went something like this:
"i've been in the navy for over 13 years, and i just spent almost $100, i tried to talk to her, but she wouldn't say anything, so i thought she was a mute, and my daughter smiled at her, but she didn't do anything, i guess it's time to get out of the service if this is how i'm going to be treated"
...needless to say i got chided for not smiling enough at customers
my solution: i taped a sign to my name tag that said "i'm smiling on the inside"
jeezuh mus h... that's great she's been in for almost 13 years, my dad's been in the army for over 20...
wow, she spent *almost* $100, i spent *almost* $300 on my ps2 back in the day
raarrgh. i hate customers and talking to people... so what do i do? i join the army to be a linguist... to talk. in other languages.
...sorry... that was long
